Meson twist-4 parton distributions in terms of twist-2 distribution amplitudes at large Nc — •Nam-Young Lee1, P.V. Pobylitsa1,2, M.V. Polyakov1,2, and K. Goeke11Institut für Theoretische Physik II, Ruhr–Universität Bochum,D–44780 Bochum, Germany — 2Petersburg Nuclear Physics Institute, Gatchina, St.Petersburg 188350, Russia

We show that in the large Nc limit four-quark twist-4 distributions in the pion can be expressed in terms of twist-2 pion distribution amplitude. This allows us to compute the isospin-2 structure function of the pion F2I=2(xB) in the large Nc limit. The method can be easily applied to other mesons as well.
